Waiting on a bus lane

[Induja]

Hello,

I got this question in a mock test :

Standing still to let someone get out is allowed…

A. … only on a bus stop
B. … only on a bus stop and on a bus lane
C. … on a bus stop, on a bus lane and on a special reserved route for buses

The answer should be B but the test says the answer is A. This is confusing, what is the right answer? And is it allowed to wait on a special reserved route too, if so then the answer should be C?

The correct answer is A

Provided that said bus stop is not situated on a bus lane or on a special reserved route for trams & busses.
